That seems to be related to opensnitch itself. And all I can gather from a brief search about it is that some opensnitch users experience an influx of eBPF errors message in case there is a version mismatch between opensnitch and the opensnitch-ebpf-module.
Here, on the other hand, I only see a single warning which might be an annoyance, indeed.
You could check your journalctl if there are more warnings / errors showing up. If there aren’t a lot I’ld tend to suppress that specific notification.
Furthermore, the mentioned eBPF module from the AUR won’t be installed as a dependency in case you’ve installed opensnitch via the extra repository. It depends on opensnitch-git which is also available in the AUR. Thus, no need to install that module if you’re using the version provided via extra.
Ohhh, I didn’t even notice the tiny header where it says opensnitch!
Had I realized it was just an error from the firewall which otherwise works fine I probably wouldn’t have even bothered making this thread, my bad.
Ok well thank you very much for expaining it, I’ll the the journal to see if any other interesting bits come up.
